上記のように構成された走行部材２ａ，２ｂは、互いに逆向きに設けられる。詳しくは、図５に示すように、吊設部材としてのカーテン３１，３２の裏側（室内側と窓側とを仕切るカーテン３１，３２において窓側）から見て、一方（図５中、左側）の走行部材２ａはステータ収容部５ｄ側（図１中、右側）が見えるように、且つ他方（図５中、右側）の走行部材２ｂは軸受収容部５ｅ側が見えるように設けられる。   The traveling members 2a and 2b configured as described above are provided in opposite directions. Specifically, as shown in FIG. 5, when viewed from the back side of the curtains 31 and 32 as suspension members (the window side in the curtains 31 and 32 separating the indoor side and the window side), one side (left side in FIG. 5) travels. The member 2a is provided so that the stator accommodating portion 5d side (right side in FIG. 1) can be seen, and the other (right side in FIG. 5) traveling member 2b is provided so that the bearing accommodating portion 5e side can be seen.

上記のように構成された走行部材２ａ，２ｂには、図示しないフック部が設けられ、該フック部にカーテン３１，３２が吊り下げ支持される。詳しくは、カーテンレール１には、カーテンを所定間隔毎に吊り下げ支持すべく複数のランナ３３（ここで言うランナは駆動源を有さないもの）が外力により走行可能に設けられ、それらの先頭に（のみ）走行部材２ａ，２ｂが設けられることになる。即ち、一方のカーテン３１は、走行部材２ａ及び複数のランナ３３に（所定間隔毎に）吊り下げ支持され、他方のカーテン３２は、走行部材２ｂ及び複数のランナ３３に（所定間隔毎に）吊り下げ支持される。   The traveling members 2a and 2b configured as described above are provided with hook portions (not shown), and the curtains 31 and 32 are suspended and supported by the hook portions. Specifically, the curtain rail 1 is provided with a plurality of runners 33 (herein, runners having no drive source) are movably supported by an external force so as to suspend and support the curtains at predetermined intervals. (Only) traveling members 2a and 2b are provided. That is, one curtain 31 is suspended and supported by the traveling member 2a and the plurality of runners 33 (at predetermined intervals), and the other curtain 32 is suspended by the traveling member 2b and the plurality of runners 33 (at predetermined intervals). Supported by lowering.

又、カーテンレール１の長手方向における両端部には、垂直方向から見て図７に模式的に示すように、長手方向の直交方向に屈曲し、ランナ３３を収容するためのランナ収容部１ｄが形成されている。   Further, at both ends of the curtain rail 1 in the longitudinal direction, runner accommodating portions 1d for accommodating the runner 33, which are bent in a direction orthogonal to the longitudinal direction as schematically shown in FIG. Is formed.

又、カーテンレール１の長手方向における両端部、詳しくはランナ収容部１ｄの下部には、図５〜図７に示すように、充電装置４１が配置（固定）されている。尚、本実施の形態では、走行部材２ａ，２ｂ及び充電装置４１が電動カーテン装置を構成している。充電装置４１は、走行部材２ａ，２ｂの移動方向の延長線上に設けられている。又、充電装置４１には、前記一対のバッテリ端子１５ａに対応した位置で外部に露出するように充電端子４１ａが配設されている。この充電端子４１ａは、出没可能に設けられ、図示しない付勢手段により突出する方向に付勢されている。充電装置４１は、走行部材２ａ，２ｂが近接すると、即ち走行部材２ａ，２ｂがカーテンレール１の端部に到達するとその充電端子４１ａがバッテリ１５のバッテリ端子１５ａと電気的に接続状態とされて該バッテリ１５を充電し、走行部材２ａ，２ｂが離間するとその充電端子４１ａがバッテリ端子１５ａと電気的に非接続状態とされる。   Moreover, as shown in FIGS. 5-7, the charging device 41 is arrange | positioned (fixed) at the both ends in the longitudinal direction of the curtain rail 1, specifically, the lower part of the runner accommodating part 1d. In this embodiment, traveling members 2a and 2b and charging device 41 constitute an electric curtain device. The charging device 41 is provided on an extension line in the moving direction of the traveling members 2a and 2b. The charging device 41 is provided with a charging terminal 41a so as to be exposed to the outside at a position corresponding to the pair of battery terminals 15a. The charging terminal 41a is provided so as to be able to appear and retract and is urged in a protruding direction by an urging means (not shown). When the traveling members 2a and 2b come close to each other, that is, when the traveling members 2a and 2b reach the end of the curtain rail 1, the charging terminal 41a is electrically connected to the battery terminal 15a of the battery 15. When the battery 15 is charged and the traveling members 2a and 2b are separated, the charging terminal 41a is electrically disconnected from the battery terminal 15a.

上記のように構成された電動カーテン装置では、例えばリモコンスイッチの操作等に基づいてバッテリ１５に接続された駆動回路１６にて高周波電圧が生成される。そして、駆動回路１６から圧電素子２５の電極板に第１の駆動周波数（超音波モータ７（ステータ２１）の第１の共振周波数ｆ１近傍にある所定範囲の周波数）の高周波電圧が印加されると、圧電素子２５にて縦振動が発生される。すると、該振動に基づいてステータ２１の変換スリット２４ａにて捩じり振動が発生される。このとき、ステータ２１（第１金属ブロック２３）の一端面の振動は、大きな捩り振動と縦振動とが合成された複合振動となっている。すると、ステータ２１の縦振動成分による浮力と捩り振動成分による推進力にてロータ２２が一方向に回転する（ステータ主体モード）。すると、ロータ２２と共に回転部材９が回転し、その出力伝達部材２９から動力が伝達され、両走行部材２ａ，２ｂがカーテンレール１の中心に向かって近接するようにそれぞれ移動（自走）する。これにより、カーテン３１，３２が開状態（広げられて窓が覆われた状態）とされる。   In the electric curtain device configured as described above, a high-frequency voltage is generated by the drive circuit 16 connected to the battery 15 based on, for example, operation of a remote control switch. Then, when a high frequency voltage having a first drive frequency (a predetermined range of frequencies in the vicinity of the first resonance frequency f1 of the ultrasonic motor 7 (stator 21)) is applied from the drive circuit 16 to the electrode plate of the piezoelectric element 25. A longitudinal vibration is generated in the piezoelectric element 25. Then, torsional vibration is generated in the conversion slit 24a of the stator 21 based on the vibration. At this time, the vibration of one end surface of the stator 21 (first metal block 23) is a composite vibration in which a large torsional vibration and a longitudinal vibration are combined. Then, the rotor 22 rotates in one direction by the propulsive force due to the buoyancy and torsional vibration components of the stator 21 (stator main mode). Then, the rotating member 9 rotates together with the rotor 22, power is transmitted from the output transmission member 29, and both the traveling members 2 a and 2 b move (self-run) so as to approach each other toward the center of the curtain rail 1. As a result, the curtains 31 and 32 are in an open state (a state where the curtains are spread and the windows are covered).

又、リモコンスイッチの操作等に基づいて駆動回路１６から圧電素子２５の電極板に第２の駆動周波数（超音波モータ７（ステータ２１）の第２の共振周波数ｆ２近傍にある所定範囲の周波数）の高周波電圧が印加されると、圧電素子２５にて縦振動が発生される。すると、該振動に基づいてステータ２１の変換スリット２４ａにて捩じり振動が発生される。このとき、ステータ２１（第１金属ブロック２３）の一端面の振動は、前記ステータ主体モードにおける捩り振動の反対方向に捩れる小さい捩り振動と縦振動とが合成された複合振動となっている。ここで、ロータ２２の共振周波数は、前記第２の駆動周波数と重なるように設定されており、ロータ２２では、前記縦振動（複合振動）に基づいて（共振して）変換スリット２２ａにて大きな捩り振動が発生される。このとき、変換スリット２２ａにて発生される捩り振動は、自身を他方向（ステータ主体モードの逆方向）に回転させるように働く振動である。よって、ステータ２１の縦振動成分による浮力と捩り振動成分による推進力とロータ２２自身の捩り振動成分にてロータ２２が他方向に回転する（ロータ主体モード）。すると、両走行部材２ａ，２ｂがカーテンレール１の異なる端部（ランナ収容部１ｄ及び充電装置４１）に向かって互いに離間するようにそれぞれ移動（自走）する。これにより、カーテン３１，３２が閉状態（カーテンレール１の異なる端部に集結されて窓が露出した状態）とされる（図６参照）。   Further, based on the operation of the remote control switch or the like, a second drive frequency (frequency within a predetermined range near the second resonance frequency f2 of the ultrasonic motor 7 (stator 21)) is applied from the drive circuit 16 to the electrode plate of the piezoelectric element 25. When a high-frequency voltage is applied, longitudinal vibration is generated in the piezoelectric element 25. Then, torsional vibration is generated in the conversion slit 24a of the stator 21 based on the vibration. At this time, the vibration of one end surface of the stator 21 (first metal block 23) is a composite vibration in which a small torsional vibration and a longitudinal vibration that are twisted in the opposite direction of the torsional vibration in the stator main mode are combined. Here, the resonance frequency of the rotor 22 is set so as to overlap with the second drive frequency, and the rotor 22 has a large resonance slit 22a based on the longitudinal vibration (composite vibration). Torsional vibration is generated. At this time, the torsional vibration generated in the conversion slit 22a is vibration that acts to rotate itself in the other direction (the reverse direction of the stator main mode). Therefore, the rotor 22 rotates in the other direction by the propulsive force generated by the longitudinal vibration component of the stator 21 and the propulsive force generated by the torsional vibration component and the torsional vibration component of the rotor 22 itself (rotor main mode). Then, both traveling members 2a and 2b move (self-propelled) so as to be separated from each other toward different end portions (runner housing portion 1d and charging device 41) of curtain rail 1. As a result, the curtains 31 and 32 are in a closed state (a state where the windows are exposed by being concentrated at different ends of the curtain rail 1) (see FIG. 6).

ここで、本実施の形態の電動カーテン装置では、前記位置把握手段（センサ用マグネット１１、ホール素子１３及びコントローラ１４）にて走行部材２ａ，２ｂの存在位置が把握され、前記制御手段（コントローラ１４及び駆動回路１６）にて前記存在位置に応じて超音波モータ７に供給される高周波電圧の周波数が変化される。   Here, in the electric curtain device according to the present embodiment, the position grasping means (the sensor magnet 11, the hall element 13 and the controller 14) grasps the positions where the traveling members 2a and 2b exist, and the control means (the controller 14). And the drive circuit 16) changes the frequency of the high-frequency voltage supplied to the ultrasonic motor 7 in accordance with the location.

そして、本実施の形態では、走行部材２ａ，２ｂがカーテンレール１の端部（充電装置４１）方向に走行しているとき、制御手段（コントローラ１４及び駆動回路１６）は、予め設定された端部近傍位置に前記存在位置が到達したと判断すると、供給する高周波電圧の周波数を前記第２の共振周波数ｆ２から遠ざけるように変化させる。よって、予め設定された端部近傍位置に前記存在位置が到達したと判断されると、超音波モータ７の出力が低くなり、速度が低下し、走行部材２ａ，２ｂがカーテンレール１の端部で停止する際の衝撃（充電装置４１と接触する際の衝撃）が抑えられる。そして、カーテンレール１の端部で停止したとき、充電端子４１ａは前記付勢手段に抗して没入した状態（図示略）となり、充電端子４１ａとバッテリ端子１５ａとが（前記付勢手段の作用にて）押圧接触され電気的に接続状態とされる。これにより、カーテン３１，３２が閉状態（カーテンレール１の異なる端部に集結されて窓が露出した状態）とされると、充電装置４１とバッテリ１５とが電気的に接続状態とされ、バッテリ１５が自動的に充電される。尚、走行部材２ａ，２ｂがカーテンレール１の端部で停止すると、前記高周波電圧の供給は停止されるが、超音波モータ７は高周波電圧の供給が停止された状態でロータ保持力を有するため、前記付勢手段にて走行部材２ａ，２ｂが押し戻される（前記押圧接触の状態が解除される）ということが防止される。   In the present embodiment, when the traveling members 2a and 2b are traveling in the direction of the end portion (charging device 41) of the curtain rail 1, the control means (the controller 14 and the drive circuit 16) are set to the preset end. When it is determined that the existence position has reached the position near the part, the frequency of the high-frequency voltage to be supplied is changed so as to be away from the second resonance frequency f2. Therefore, when it is determined that the existing position has reached a preset position near the end, the output of the ultrasonic motor 7 is decreased, the speed is decreased, and the traveling members 2a and 2b are connected to the end of the curtain rail 1. The impact when stopping at (the impact when contacting the charging device 41) is suppressed. And when it stops at the edge part of the curtain rail 1, the charging terminal 41a will be in the state (illustration omitted) against the said energizing means, and the charging terminal 41a and the battery terminal 15a (action of the said energizing means). )) Is pressed and brought into electrical connection. As a result, when the curtains 31 and 32 are in a closed state (a state where the windows are exposed at different ends of the curtain rail 1), the charging device 41 and the battery 15 are electrically connected to each other, and the battery 15 is automatically charged. When the traveling members 2a and 2b stop at the end of the curtain rail 1, the supply of the high-frequency voltage is stopped, but the ultrasonic motor 7 has a rotor holding force in a state where the supply of the high-frequency voltage is stopped. Thus, it is possible to prevent the traveling members 2a and 2b from being pushed back by the biasing means (the state of the pressing contact is released).

次に、上記実施の形態の特徴的な作用効果を以下に記載する。
（１）走行部材２ａ，２ｂがバッテリ１５を有し、カーテンレール１の端部には充電装置４１が設けられる。よって、走行部材２ａ，２ｂのバッテリ１５を充電装置４１にて充電させ、走行部材２ａ，２ｂを自身のバッテリ１５の電力により走行させることができる。これにより、走行する走行部材２ａ，２ｂに対して外部からの電源供給用の配線を接続状態としておく必要がない。即ち、従来技術に対して電源供給用の配線が不要となる。このように電源供給用の配線が不要である（配線がない）ため、取り付け時等の取り扱いが容易となる。又、カーテンレール１に配線を隠すための細工等を施すことなく、外観を良好とすることができる。 Next, characteristic effects of the above embodiment will be described below.
(1) The traveling members 2 a and 2 b have a battery 15, and a charging device 41 is provided at the end of the curtain rail 1. Therefore, the battery 15 of the traveling members 2a and 2b can be charged by the charging device 41, and the traveling members 2a and 2b can be driven by the electric power of the battery 15 of their own. Thereby, it is not necessary to make the wiring for the power supply from the outside into the connection state with respect to the traveling members 2a and 2b that travel. That is, the power supply wiring is not required for the conventional technology. In this way, no wiring for power supply is required (no wiring), so that handling during installation and the like is easy. In addition, the appearance can be improved without performing any work or the like for hiding the wiring on the curtain rail 1.

（２）充電装置４１は、カーテンレール１の端部に配置されるため、カーテンレール１の中央部に配置されたものに比べて、外観が良好となる。又、充電装置４１は、カーテンレール１の端部に配置されるため、走行部材２ａ，２ｂがカーテンレール１の端部に到達した際に、走行部材２ａ，２ｂ（超音波モータ７）の駆動力を利用して充電装置４１の充電端子４１ａとバッテリ１５のバッテリ端子１５ａとを押圧接触させて容易に接続状態とすることが可能となる。   (2) Since the charging device 41 is disposed at the end of the curtain rail 1, the appearance is better than that disposed at the center of the curtain rail 1. Moreover, since the charging device 41 is disposed at the end of the curtain rail 1, when the traveling members 2a and 2b reach the end of the curtain rail 1, the driving members 2a and 2b (ultrasonic motor 7) are driven. Using the force, the charging terminal 41a of the charging device 41 and the battery terminal 15a of the battery 15 can be pressed and brought into contact with each other easily.

（３）充電装置４１は、走行部材２ａ，２ｂがカーテンレール１の端部に到達するとその充電端子４１ａがバッテリ１５のバッテリ端子１５ａと電気的に接続状態とされて該バッテリ１５を充電し、走行部材２ａ，２ｂが離間するとその充電端子４１ａがバッテリ端子１５ａと電気的に非接続状態とされる。よって、走行部材２ａ，２ｂがカーテンレール１の端部に到達すれば、バッテリ１５が自動的に充電される。   (3) When the traveling members 2a and 2b reach the end of the curtain rail 1, the charging device 41 is electrically connected to the battery terminal 15a of the battery 15 to charge the battery 15, When the traveling members 2a and 2b are separated from each other, the charging terminal 41a is electrically disconnected from the battery terminal 15a. Therefore, when the traveling members 2a and 2b reach the end of the curtain rail 1, the battery 15 is automatically charged.

（４）走行部材２ａ，２ｂが備えるアクチュエータを超音波モータとしたため、直流モータ等を用いた場合に比べて、作動音を小さくすることができる。又、超音波モータ７はトルクが大きいため、減速機構を省略することができる。又、走行部材２ａ，２ｂに駆動回路１６を設けたため、走行部材２ａ，２ｂ毎で高周波電圧が生成され、超音波モータ７毎に適した周波数の高周波電圧を供給することができる。   (4) Since the actuator provided in the traveling members 2a and 2b is an ultrasonic motor, the operating noise can be reduced as compared with the case where a DC motor or the like is used. Further, since the ultrasonic motor 7 has a large torque, the speed reduction mechanism can be omitted. Further, since the driving circuit 16 is provided in the traveling members 2a and 2b, a high-frequency voltage is generated for each traveling member 2a and 2b, and a high-frequency voltage having a frequency suitable for each ultrasonic motor 7 can be supplied.

（５）位置把握手段（センサ用マグネット１１、ホール素子１３及びコントローラ１４）にて走行部材２ａ，２ｂの存在位置が把握され、制御手段（コントローラ１４及び駆動回路１６）にて前記存在位置に応じて超音波モータ７に供給される高周波電圧の周波数が変化されるため、前記存在位置に応じて超音波モータ７の出力が変化される。よって、単に一定（一定周波数）の高周波電圧が供給され一定出力を発生する超音波モータを備えた走行部材に比べて、種々の問題を解決することができる。又、本実施の形態では、走行部材２ａ，２ｂがカーテンレール１の端部で停止する際の衝撃（充電装置４１と接触する際の衝撃）が抑えられる。   (5) The existence position of the traveling members 2a and 2b is grasped by the position grasping means (the sensor magnet 11, the hall element 13 and the controller 14), and the control means (the controller 14 and the drive circuit 16) responds to the existence position. Since the frequency of the high-frequency voltage supplied to the ultrasonic motor 7 is changed, the output of the ultrasonic motor 7 is changed according to the existing position. Therefore, various problems can be solved as compared with a traveling member provided with an ultrasonic motor that simply supplies a constant (constant frequency) high-frequency voltage and generates a constant output. Moreover, in this Embodiment, the impact at the time of travel member 2a, 2b stopping at the edge part of the curtain rail 1 (impact at the time of contacting with the charging device 41) is suppressed.

上記実施の形態は、以下のように変更してもよい。
・上記実施の形態では、充電装置４１は、カーテンレール１の端部に配置（固定）されるとしたが、これに限定されず、例えばカーテンレールの中間部に配置してもよい。尚、この場合、バッテリ１５と充電装置４１とを電気的に接続するための（バッテリ端子１５ａや充電端子４１ａの）構成を変更する必要がある。又、充電装置４１は、走行部材２ａ，２ｂの走行範囲の少なくとも一部に配置されればよく、カーテンレール１に固定しなくても例えば建物の壁等に固定してもよい。 The above embodiment may be modified as follows.
-In above-mentioned embodiment, although the charging device 41 was arrange | positioned (fixed) at the edge part of the curtain rail 1, it is not limited to this, For example, you may arrange | position in the intermediate part of a curtain rail. In this case, it is necessary to change the configuration for electrically connecting the battery 15 and the charging device 41 (for the battery terminal 15a and the charging terminal 41a). Moreover, the charging device 41 should just be arrange | positioned in at least one part of the traveling range of traveling member 2a, 2b, and may be fixed to the wall of a building, etc., without fixing to the curtain rail 1. FIG.

・上記実施の形態では、充電装置４１は、走行部材２ａ，２ｂがカーテンレール１の端部に到達するとその充電端子４１ａがバッテリ１５のバッテリ端子１５ａと電気的に接続状態とされて該バッテリ１５を自動的に充電するとしたが、これに限定されない。例えば、何らかの操作（例えばリモコンスイッチの操作や手動による接続操作）に基づいて充電するようにしてもよい。   In the above embodiment, when the traveling members 2 a and 2 b reach the end of the curtain rail 1, the charging terminal 41 is electrically connected to the battery terminal 15 a of the battery 15 and the battery 15 Is automatically charged, but is not limited to this. For example, charging may be performed based on some operation (for example, operation of a remote control switch or manual connection operation).

・上記実施の形態では、充電端子４１ａとバッテリ端子１５ａとを接触させることで充電装置４１とバッテリ１５とを電気的に接続状態とするとしたが、非接触（磁気誘電による充電方式等）で充電装置とバッテリとを電気的に接続状態とするようにしてもよい。尚、勿論、この場合、充電端子４１ａ及びバッテリ端子１５ａを設ける必要はなく、更に外観を良好とすることができる。   In the above embodiment, the charging device 41 and the battery 15 are electrically connected by bringing the charging terminal 41a and the battery terminal 15a into contact with each other, but charging is performed in a non-contact manner (such as a charging method using a magnetic dielectric). The device and the battery may be electrically connected. Of course, in this case, it is not necessary to provide the charging terminal 41a and the battery terminal 15a, and the appearance can be further improved.

・上記実施の形態の走行部材２ａ，２ｂに、バッテリ１５を充電するためのソーラーパネルを追加して設けてもよい。尚、この場合、カーテン３１，３２（吊設部材）の裏側（室内側と窓側とを仕切るカーテン３１，３２において窓側（窓の外側））から見て、ソーラーパネルが見えるように設けるのが望ましい。このようにすると、ソーラーパネルによりバッテリを充電（太陽光充電）させることができる。よって、省エネルギー化を図ることができる。又、例えば、走行部材が自身のバッテリと充電装置とを（接触又は非接触で）電気的に接続状態とできない箇所（例えばカーテンレール１の中間部）に滞在している場合でも、ソーラーパネルにてバッテリを充電させることで、走行部材が走行不能（充電量が０）となることを防止することができる。   -You may provide additionally the solar panel for charging the battery 15 in the traveling members 2a and 2b of the said embodiment. In this case, it is desirable to provide the solar panel so that it can be seen from the back side of the curtains 31 and 32 (hanging members) (from the window side (outside the window) in the curtains 31 and 32 separating the indoor side and the window side). . If it does in this way, a battery can be charged (solar charge) by a solar panel. Therefore, energy saving can be achieved. In addition, for example, even when the traveling member stays in a place where the battery and the charging device of the traveling member cannot be in an electrically connected state (contact or non-contact) (for example, an intermediate portion of the curtain rail 1), By charging the battery, it is possible to prevent the traveling member from traveling (charging amount is 0).

・上記実施の形態の電動カーテン装置（吊設部材駆動装置）は、カーテンレール１の端部（走行部材の走行範囲の少なくとも一部）に配置される充電装置を備えるとしたが、走行部材に、バッテリを充電するためのソーラーパネルを設け、充電装置を省略してもよい。尚、この場合、カーテン（吊設部材）の裏側（室内側と窓側とを仕切るカーテンにおいて窓側（窓の外側））から見て、ソーラーパネルが見えるように設けるのが望ましい。このようにすると、ソーラーパネルによりバッテリを充電（太陽光充電）させることができる。これにより、走行する走行部材に対して外部からの電源供給用の配線を接続状態としておく必要がない。即ち、従来技術に対して電源供給用の配線が不要となる。   -Although the electric curtain apparatus (hanging member drive device) of the said embodiment was provided with the charging device arrange | positioned at the edge part (at least one part of the traveling range of a traveling member) of the curtain rail 1, A solar panel for charging the battery may be provided, and the charging device may be omitted. In this case, it is desirable to provide the solar panel so that it can be seen from the back side of the curtain (hanging member) (from the window side (outside the window) in the curtain separating the indoor side and the window side). If it does in this way, a battery can be charged (solar charge) by a solar panel. Thereby, it is not necessary to keep the power supply wiring from the outside connected to the traveling member that travels. That is, the power supply wiring is not required for the conventional technology.

・上記実施の形態では、走行部材２ａ，２ｂが備えるアクチュエータを超音波モータとしたが、他のアクチュエータ（例えば直流モータ）に変更してもよい。尚、直流モータに変更した場合、駆動回路１６を設けて高周波電圧を生成する必要はない。このようにすると、一般的な直流モータに変更することなどにより、電動カーテン装置を安価にすることができる。   In the above embodiment, the actuator provided in the traveling members 2a and 2b is an ultrasonic motor, but may be changed to another actuator (for example, a DC motor). In addition, when it changes to a direct current motor, it is not necessary to provide the drive circuit 16 and to generate a high frequency voltage. If it does in this way, an electric curtain apparatus can be made cheap by changing to a common direct current motor.

・上記実施の形態では、位置把握手段（センサ用マグネット１１、ホール素子１３及びコントローラ１４）にて走行部材２ａ，２ｂの存在位置を把握し、前記存在位置に応じて超音波モータ７の出力を変化させる構成としたが、これに限定されない。例えば、単に一定（一定周波数）の高周波電圧を超音波モータ７に供給するように変更してもよい。又、位置把握手段は、前記存在位置を把握することができれば、他の構成に変更してもよい。   In the above embodiment, the position of the traveling members 2a and 2b is grasped by the position grasping means (the sensor magnet 11, the hall element 13 and the controller 14), and the output of the ultrasonic motor 7 is output according to the existence position. Although it was set as the structure changed, it is not limited to this. For example, it may be changed so that a constant (constant frequency) high-frequency voltage is supplied to the ultrasonic motor 7. The position grasping means may be changed to another configuration as long as it can grasp the existence position.

・上記実施の形態では、カーテンレール１を略直線状のものとしたが、曲線部を有したものに変更してもよい。尚、本実施の形態の走行部材２ａ，２ｂは、支持部４ａと延設部４ｂとが垂直の軸中心に回転可能に連結され、ランナ３に対してケース５が垂直の軸中心に回転可能とされるため、曲線部を有したカーテンレールに設けても、走行部材２ａ，２ｂが曲線部に追従して滑らかに走行可能となる。   In the above embodiment, the curtain rail 1 is substantially linear, but may be changed to one having a curved portion. In the traveling members 2a and 2b of the present embodiment, the support portion 4a and the extending portion 4b are rotatably connected to a vertical axis center, and the case 5 can be rotated about the vertical axis center with respect to the runner 3. Therefore, even if it is provided on the curtain rail having a curved portion, the traveling members 2a and 2b can smoothly travel following the curved portion.

・上記実施の形態では、本発明を電動カーテン装置に具体化したが、カーテン以外の吊設部材をレールに沿って移動させる他の吊設部材駆動装置に具体化してもよい。
上記各実施の形態及び別例から把握できる技術的思想について、以下にその効果とともに記載する。 In the above embodiment, the present invention is embodied in the electric curtain device, but may be embodied in another hanging member driving device that moves the hanging member other than the curtain along the rail.
The technical idea that can be grasped from the above-described embodiments and other examples will be described below together with the effects thereof.

（イ）請求項６又は７に記載の吊設部材駆動装置において、前記レールに対する前記走行部材の存在位置を把握する位置把握手段と、前記存在位置に応じて前記超音波モータに供給する高周波電圧の周波数を変化させる制御手段とを備えたことを特徴とする吊設部材駆動装置。このようにすると、位置把握手段にて走行部材の存在位置が把握され、制御手段にて前記存在位置に応じて超音波モータに供給される高周波電圧の周波数が変化されるため、前記存在位置に応じて超音波モータの出力が変化される。よって、例えば、レールの端部で停止する際の衝撃が大きくなるといったことを防止することができ、単に一定の高周波電圧が供給され一定出力を発生する超音波モータを備えた走行部材に比べて、種々の問題を解決することができる。特に、請求項２に記載の構成にこの構成が適用されることで、走行部材がレールの端部で充電装置と接触する際の衝撃等を抑えることができるといった作用効果も得られるようになる。   (A) In the hanging member driving apparatus according to claim 6 or 7, a position grasping means for grasping a position where the traveling member is present with respect to the rail, and a high-frequency voltage supplied to the ultrasonic motor according to the position. And a control means for changing the frequency of the suspension member drive device. In this way, the position grasping means grasps the presence position of the traveling member, and the control means changes the frequency of the high-frequency voltage supplied to the ultrasonic motor according to the existence position. Accordingly, the output of the ultrasonic motor is changed. Therefore, for example, it is possible to prevent an increase in impact when stopping at the end of the rail, compared to a traveling member equipped with an ultrasonic motor that simply supplies a constant high-frequency voltage and generates a constant output. Various problems can be solved. In particular, by applying this configuration to the configuration according to claim 2, it is possible to obtain an operational effect such that an impact or the like when the traveling member contacts the charging device at the end of the rail can be suppressed. .
